The Problem: LLMs are terrible at understanding eCommerce sites. They: Hallucinate prices/specs from messy HTML Waste tokens on UI boilerplate (headers, popups, ads) Struggle with real-time inventory/pricing updates

Our solution: A fork of Answer.AI’s llms.txt that introduces site-llms.xml, an XML sitemap protocol for product data.

Stores expose: /site-llms.xml: Index of all product URLs /product/123/llms.txt: Clean Markdown with specs/pricing (example in repo)

Benefits: AI gets structured data instead of scraping Stores control what’s exposed (like robots.txt) Scales to millions of products (sitemap indexes supported)

We’re open-sourcing this under CC BY-SA (same as sitemap protocol). Would love HN’s thoughts:

Is this the right abstraction? Could it work for non-eCommerce sites?
